1. Battery leakage When there is a lot of water inside the battery, the electrolyte inside the battery reacts with water, resulting in gas and hydrofluoric acid. Hydrofluoric acid is a highly corrosive acid that can cause corrosion of metal parts inside the battery, ultimate...

4. Choose products that offer warranty services and product liability insurance. Precautions for using lithium-ion battery products: 1. Before use, carefully read the instruction manual and the warning words listed, and truly use according to the instructi...

Precautions for purchasing lithium-ion battery mobile power supply: 1. Check if there is a Chinese user manual, product instructions on the packaging, or accompanying product usage instructions and precautions. 2. Products that are imported or manufactured...

(3) Spinel lithium manganese oxide Li2Mn2O4, with low voltage (3V), low customer volume, and poor circulation, are all being studied on how to prevent the occurrence of such things. Ternary: In order to solve the defects of layered lithium manganate, Ni and Co (Al) were invented by doping meta...

The advantages of lithium manganese oxide are good rate performance, easy preparation, and low cost. The disadvantage is that the dissolution of manganese leads to poor high-temperature performance and cycling performance. By doping aluminum and sintering granulation, the high-temperature perf...

4. Long lifespan, more charging and discharging cycles are better As a general requirement, lithium iron phosphate battery packs still have 85% capacity after 2000 1C discharges, and 80% capacity after 3000 discharges. Of course, each manufacturer sets different standards du...

2. Self discharge rate of lithium iron phosphate batteries Due to the high power consumption of lithium iron phosphate batteries, it is required that the self-discharge rate of the battery pack should be less than 2% per month. To achieve this, the above consistency requirem...

1. Consistency of battery cells in lithium iron phosphate batteriesIf there is a protective plate with poor consistency in the battery cells of lithium iron phosphate batteries, according to the water bucket principle, its capacity will be manifested as the overall capacity of the lowest capacity ba...

▲ Check the battery casing. In many cases, the damage to the battery casing is due to improper battery installation, welding slag in the frame of the battery box, and low chassis caused by collision.▲ Open the cover plate to check for any traces of acid leakage around the safety valve, and then op...

1、 During the battery manufacturing process, if the following problems occur, it may lead to battery leakage: 1. When welding the battery shell and battery cover, the welding is not firm, the sealing is not good, and there are problems such as missed welding, false welding,...
